After graduating from the Faculty of Organic Compounds Technology, Gheorghe Asachi Technical University, Iaşi, I was hired by the Petru Poni Institute of Macromolecular Chemistry in Iaşi, where I am still working. I received my PhD in 1995 from Ghent University, Belgium, followed by several postdoctoral stages at the Institute of Biological and Technological Chemistry Oeiras, Portugal and Montreal University, Canada. My expertise includes: polymers with hypocholesterolemic activities—bile acid adsorbents and cholesterol solubilizers; nonionic or ionic amphiphilic polymers obtained by chemical modification of polysaccharides and their self-aggregation or mixed aggregation with surfactants by fluorescence, conductometry, viscometry, surface tension measurements, and light scattering; block copolymers from polysaccharides and bile acid polyesters, their self-aggregation characterization and evaluation of application as drug delivery systems, flocculants/dispersants, and nanoreactors; and oligomers and polymers with antimicrobial properties. I am the author of 82 articles, five book chapters, and 14 patents.
